The degree of transparency of any of the layers can be changed so that the
layer(s) beneath are visible, semi-visible or invisible. As an example, if layer
“A” above were expanded to cover all of the available image area and made
fully opaque, none of the layers beneath it would be visible. By the same
token, if Layer “A” were made semi-transparent, the layers beneath would be
dimly visible. Should layer “A” be made fully transparent, then it would seem
to disappear completely.
The powerful Keyer function of the C2-7000 series takes advantage of this
feature to superimpose portions of one window over another. Portions of a
layer are made semi-transparent or invisible. Certain colors are made invisible
the result is one image appears to float above another on the layer stack.
3.9 Modes
The three modes available in the C2-7000 series are Switcher Mode,
Independent Mode and Dual Picture in Picture (Dual PIP) mode.
3.9.1 Switcher Mode
The switcher mode configures the two outputs to function in a familiar preview
and program arrangement. The output in this mode is actually a display of a
single Window (A), optional Lock Source (Z) and optional Logo (a). The
Window (B) and Logo (b) are used internally for program / preview processing
and as such are unavailable to the user.
When an input selection is made, it instantly appears on Output 2––a Preview
Output––but no action is taken on Output 1. The “Program” Output (Output 1)
retains the last image selected when in the Switcher mode until the user
presses button number 2 on the front panel. Button number 2 is the ‘Take”
button when in the Switcher mode and pressing it causes the image present
on Output 2 to also appear on Output 1. Special control logic within the C2-
